"It's disappointing, it's just same old same old with Arsenal," Merson told BBC Radio 5 Live.

"I just though last night Arsene was a bit beaten up, he looked lost last night. I've seen him [Wenger] lose games before, but I think last night he looked bit more lost than what he's been for a long time.

"It's like a marriage! It's 20 years! He's not got a lot else, that's his life, Arsenal is his life. I don't think people understand how much he gives to that club."

Merson was also asked about Arsenal's upcoming game against Sutton United in the FA Cup and, in particular, the Gunners were to do the unthinkable and lose the game.
